msm: pcie: update debugfs messages with new IPC label
In addition to having outputs to kernel log, PCIe debugfs messages should also be captured in IPC logging. Therefore, add a new IPC logging label and update the existing calls to do so. Change-Id: I2ab6a6549575c4e2de2f1ef0756328f4b6f6a178 Signed-off-by: Tony Truong <truong@codeaurora.org>
